The Meditherapy Retinal Skin Booster Serum is a lightweight, non-sticky serum designed to enhance skin texture and address signs of aging. Formulated with retinaldehyde, a derivative of vitamin A, it aims to promote collagen production and reduce the appearance of fine lines and wrinkles. 
Texture & Absorption
Users have praised the serum for its lightweight consistency, noting that it absorbs quickly without leaving a sticky residue. This makes it suitable for layering under other skincare products or makeup. 
Efficacy
Some users have reported noticeable improvements in skin firmness and a reduction in fine lines after consistent use. One reviewer mentioned experiencing “tighter skin” and fewer wrinkles. 
However, it’s important to note that the serum contains 0.01% retinaldehyde, which is below the commonly recommended effective concentration of 0.05%. This lower percentage may result in more subtle effects, especially for those accustomed to higher-strength retinoid products. 
Suitability for Sensitive Skin
The serum includes Centella Asiatica extract, known for its calming properties, making it potentially suitable for individuals with sensitive skin. Many users have reported no irritation, even with regular use. 
Conclusion
The Meditherapy Retinal Skin Booster Serum offers a gentle introduction to retinaldehyde-based skincare. Its lightweight formula and inclusion of soothing ingredients make it appealing for those with sensitive skin or individuals new to retinoids. However, those seeking more pronounced anti-aging effects might consider products with higher concentrations of active ingredients.
Here are some additional cons of the Meditherapy Retinal Skin Booster Serum:
1. Slow Visible Results – Since the concentration of retinaldehyde is low, it may take weeks or even months to see significant changes in skin texture and fine lines.
2. Not a True Anti-Aging Powerhouse – While it’s marketed for anti-aging, the formula might be too mild for those with deep wrinkles or advanced signs of aging who need a stronger retinoid.
3. Potential for Mild Irritation – Despite being a gentler formula, some users with very sensitive skin might still experience dryness, redness, or peeling, especially if they don’t ease into usage properly.
4. Not a One-Step Solution – This serum needs to be paired with other hydrating or barrier-supporting products (like a moisturizer and SPF) to prevent dryness, making it less convenient for minimalists.
